Gigabit Power Injector Block Diagram
Description of LED Functions for Gigabit Power Injector
Power-up Sequence:
Upon power-up, all 3 LEDs will light for 2 seconds, as part of the self-test for the
internal microprocessor software. After the end of the 2 seconds, the "ON" LED
will illuminate green, signifying that the DC output voltage is available for
powering a compliant load (to the 802.3af PoE standards).
Dimension Diagram Unit: mm (inch)

Detection Sequence:
Once a compliant load is attached to the output RJ45 connector, the green
"CONNECT" LED will illuminate.
Should the load be non-compliant then the LEDs will blink a code signifying the
cause for non-detection.
Detection Failure Codes:
1. Incorrect resistive signature –The green “CONNECT” and red “FAULT” LEDs will
blink 3 times.
2. Incorrect capacitive signature –The green “ON” LED will blink 3 times.
3. Incorrect Voffset –The green “CONNECT” and green “ON” LEDs will blink 3 times.
4. Unstable current measurement –The green “ON” LED will blink 3 times
5. Low voltage sensed during detection (overload) –The red “FAULT” LED will blink 3
times
After the LEDs blink 3 times the Power Injector will continue to try to detect a
valid load. Therefore, until the correct load is applied, the LEDs will continue to
blink. If there is an open circuit connected to the output RJ45 then the LEDs will
not blink but the Power Injector will continue to try to detect a valid load.
Fault Sequence:
Should there be a fault such as an overload or short circuit then the red
"FAULT" LED will illuminate. The red “FAULT” LED will illuminate for 2
seconds and then go off as the power supply tries to redetect a valid load. If there
is a problem in detecting, the LED will indicate what is wrong with the load as
per the codes in the section above.

The model has/The models in this product series have been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
—Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications to equipment not expressly approved by PHIHONG could void the user’s authority to operate the
equipment.
